Insights

MicroRNAs (miRNAs) are key regulators in cancer. This review focuses on miR-424, exploring its dual role in cancer development and its potential as a diagnostic and therapeutic target in malignancies.

Area of Science:

  • Molecular Biology
  • Oncology
  • Biochemistry

Background:

  • MicroRNAs (miRNAs) are endogenous, noncoding RNAs with critical roles in cellular processes.
  • miRNAs exhibit both tumor-suppressive and oncogenic functions, significantly impacting cancer development and progression.
  • Dysregulation of miRNA expression is a hallmark of many malignancies.

Purpose of the Study:

  • To review recent studies on the role of miR-424 in cancer modulation.
  • To explore the clinical potential of miR-424 in cancer diagnosis and therapy.
  • To highlight the dualistic nature of miR-424 in different cancer types.

Main Methods:

  • Systematic literature review of studies published between 2013 and 2020.
  • Analysis of miR-424's molecular mechanisms and target pathways.
  • Evaluation of miR-424's clinical relevance in cancer.

Main Results:

  • miR-424 regulates key cancer-related pathways including p53, PI3K/Akt, and Wnt.
  • It influences cellular growth, apoptosis, differentiation, chemoresistance, and cancer immunity.
  • miR-424 acts as a tumor suppressor in some cancers and an oncogene in others.

Conclusions:

  • miR-424 plays a complex, context-dependent role in carcinogenesis.
  • Its cancer-dependent function suggests potential as a prognostic and diagnostic biomarker.
  • miR-424 represents a promising candidate for novel cancer treatment strategies.

MicroRNAs01:22

MicroRNAs

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Mitogens and the Cell Cycle02:38

Mitogens and the Cell Cycle

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...

Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...
